Beyonce and Friends Sing for the Obamas

Welcoming the new President of the United States, Beyonce Knowles and friends took the stage at the Neighborhood Ball in Washington DC on Tuesday night (January 20).

After an introduction from actor Denzel Washington, Barack took over the mic for an impromptu speech, saying, "First of all, how good looking is my wife?"

Ready for their first dance as President and First Lady, the Obamas then showed off their moves as Beyonce, clad in a full-length cream satin dress, sang a stirring performance of the Etta James classic "At Last", bringing a crowd including the Obamas, Denzel and Mary J Blige nearly to tears.
